Is this normal for HG?

I am feeling super weak. I have to have my husband take me to the bathroom, I have to have my husband help me to bed, have him get me food and water, etc. my obgyn keeps saying it will go away soon. I am 15 weeks and I’m still miserable. I can’t eat without puking. I can’t sit up without feeling dizzy. The reason my husband has to help me is because I get incredibly shaky. When I get shaky I end up falling. I have passed out a few times due to being so seriously dehydrated.
